--------------------------------
Summary: Increase retention of applications in AppManager without
sending more applications to the UI
Key: YARN-256
URL: https://issues.apache.org/jira/browse/YARN-256
Project: Hadoop YARN
Issue Type: Improvement
Affects Versions: 0.23.5
Reporter: Derek Dagit
In very busy clusters we would like to retain applications longer so that
users' links will not expire too soon. Very often links to application history
expire before they can be followed.
Simply increasing max-completed applications has an adverse performance impact
on the applications list in the web UI because it presents the entire list of
applications with a request.
Therefore, we would like some way to be able to increase the retention of
applications without increasing the number of applications sent to the Web UI.
